CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 356,428, dated January 18, 1887.

Application filed November 12 1886. Serial No.21i666.

United States, residing in the city and countyof Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Oar-Couplings, which improvement is l'ully` set forth in the following specification and accompanying drawings, in which- Figure l represents a partial top or lplan view and partial horizontal section of a carcoupling embodying our invention. Fig. 2 represents a partial front and partial vertical section thereof on an enlarged scale.

Similar letters of reference indicate corre sponding parts'in the two gures.

Our invention consists of a coupling-bar which is pivoted to the draw-head and pressed by springs in opposite directions, whereby a car may be automatically coupled and readily uncoupled,as will be hereinafter fully set forth.

It also consists of the construction of the coupling bar, whereby uncoupling is prevented, as will be hereinafter set forth.

It also consists of means for disengaging the coupliugbars and holding them in uncoupled position, as will be hereinafter fully set forth.

Referring to the drawings, A represents draw-heads, which are fitted to and slide in the bumpers B, and bear against the springs O, after the manner of draw-heads in general use.

Pivoted to the draw-heads are coupling-bars D, which project outwardly from said heads,

and have inclined or rounded noses E, which interlock, as is well known in car-couplers of this class; the inner or heel end ol' each coupling-bar are springs F G, which are secured to the drawhead, the spring F being superior in pressure to the spring G. Connected with the spring F is a cord or chain, H, which is attached to a lever, J, the latter being pivoted to the side of the bumper, so as to be conveniently reached and movable in a keeper, K, which is secured to the bumper and provided with a shoulder, L, for locking said lever when t-he bar D is in uncoupled position.

It will be seen that the cars are coupled, as

' 5o shown in Fig. 1, in which position of parts therein the noses of thebars D interlock, they being held together by the action of the su- Bearing against opposite sides of f (No model.)

perior springs F, said bars being, however, permitted to oscillate, due to the swaying motions of the cars, both springs F and G yielding during said motions.

When it is desired to uncouple the cars, they being sufficiently close to permit the shoulders or backs of the noses ot' the bars D to clear each other when moved laterally, the levers J, one or both, are operated, whereby they withdraw the springs F from the couplingbars. The springs G then.immediately control the inner ends of said bars and force the outer ends thereof from each other, thus separating said bars and automatically un.

they are embraced by the flanges, they areprevented from vertical displacement, said noses being also rounded, so as to roll while in contact with the sides of the opposite bars.

Having thus described our invention, what we claim as new, and desire to secure by Let' ters Patent, is-

1. A car-couplinghavinga pivoted bar with springs bearing laterally against the same in opposite directions, one of said springs being superior or of greater action than the other spring, substantially as described.

2. A car-coupling having a coupling-bar pivoted to the draw-head, springs bearing lat` erally against said bar in opposite directions,

and a chain attached toone of said springs for moving the latter, whereby the other spring automatically operates the bar and uncouples the car, substantially as described.

3. A couplingbar having a nose and side flanges, the latter guarding the top and bottom of the nose of the opposite bar, substantially as described.
